STEP 0: Pre-Calculation Summary

Formula Used

EMF of Cell = (([R]*Temperature)/[Faraday])*(ln(Cathodic Ionic Activity/Anodic Ionic Activity))
EMF = (([R]*T)/[Faraday])*(ln(a₂/a₁))
This formula uses 2 Constants, 1 Functions, 4 Variables

Constants Used

[Faraday] - Faraday constant Value Taken As 96485.33212
[R] - Universal gas constant Value Taken As 8.31446261815324

Functions Used

ln - The natural logarithm, also known as the logarithm to the base e, is the inverse function of the natural exponential function., ln(Number)

Variables Used

EMF of Cell - (Measured in Volt) - The EMF of Cell or electromotive force of a cell is the maximum potential difference between two electrodes of a cell.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
Cathodic Ionic Activity - (Measured in Mole per Kilogram) - Cathodic Ionic Activity is the measure of the effective concentration of a molecule or ionic species in a cathodic half-cell.
Anodic Ionic Activity - (Measured in Mole per Kilogram) - The Anodic Ionic Activity is the measure of the effective concentration of a molecule or ionic species in an anodic half cell.

STEP 1: Convert Input(s) to Base Unit

Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required
Cathodic Ionic Activity: 0.36 Mole per Kilogram --> 0.36 Mole per Kilogram No Conversion Required
Anodic Ionic Activity: 0.2 Mole per Kilogram --> 0.2 Mole per Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

EMF = (([R]*T)/[Faraday])*(ln(a₂/a₁)) --> (([R]*85)/[Faraday])*(ln(0.36/0.2))

Evaluating ... ...

EMF = 0.00430538054187815

STEP 3: Convert Result to Output's Unit

0.00430538054187815 Volt --> No Conversion Required

FINAL ANSWER

0.00430538054187815 ≈ 0.004305 Volt <-- EMF of Cell

What is Concentration cell without transference?

A cell in which the transference of a substance from a system of high concentration to one at low concentration results in the production of electrical energy is called a concentration cell. It consists of two half cells having two identical electrodes and identical electrolytes but with different concentrations. EMF of this cell depends upon the difference of concentration. Concentration cell without transference is no direct transference of electrolyte but it occurs due to the result of the chemical reaction. Each electrode is reversible with respect to one of the ions of the electrolyte.

How to Calculate EMF of Concentration Cell without Transference given Activities?

EMF of Concentration Cell without Transference given Activities calculator uses EMF of Cell = (([R]*Temperature)/[Faraday])*(ln(Cathodic Ionic Activity/Anodic Ionic Activity)) to calculate the EMF of Cell, The EMF of concentration cell without transference given activities formula is defined as the relation with the ionic activity of cathodic and anodic electrolyte at a particular temperature. EMF of Cell is denoted by EMF symbol.

How to calculate EMF of Concentration Cell without Transference given Activities using this online calculator? To use this online calculator for EMF of Concentration Cell without Transference given Activities, enter Temperature (T), Cathodic Ionic Activity (a₂) & Anodic Ionic Activity (a₁) and hit the calculate button. Here is how the EMF of Concentration Cell without Transference given Activities calculation can be explained with given input values -> 0.004305 = (([R]*85)/[Faraday])*(ln(0.36/0.2)).

FAQ
